The vehicle dispatch position transmission unit 11 is mainly realized by the processor 101 that operates the communication interface 104 while referring to the memory 102 and the storage 103. The vehicle dispatch position is a position in which a dispatch vehicle is to be dispatched, and is a position in which the user gets on the vehicle. For example, the vehicle dispatch position is specified by a user operation. For example, a position in which the user performs an operation for tapping their finger on a map displayed on the user interface 105 of the user device 10 becomes the vehicle dispatch position. The vehicle dispatch position may be determined based on a position of the GPS receiving device included in the user device 10.

The candidate reception unit 13 receives information regarding the autonomous driving function of at least one candidate vehicle in association with the at least one candidate vehicle from the server 30. The candidate reception unit 13 is mainly realized by the processor 101 that operates the communication interface 104 while referring to the memory 102 and the storage 103. The candidate vehicles are vehicles as candidates of the dispatch vehicle. The information regarding the autonomous driving function is information regarding the ability or reliability of autonomous driving. As a specific example of the information regarding the autonomous driving function, the presence or absence of the autonomous driving function, dimension information, and autonomous driving history. The details of the information regarding the autonomous driving function will be described below. The “candidate reception unit receives information regarding the autonomous driving function of at least one candidate vehicle in association with the at least one candidate vehicle” means that the candidate reception unit receives the information so as to determine which candidate vehicle is the information regarding the autonomous driving function such as information of the first candidate vehicle and information of the second candidate vehicle. For example, the candidate reception unit 13 receives a vehicle identification number of the candidate vehicle in association with the information regarding the autonomous driving function.

The display control unit 14 displays the information regarding the autonomous driving function of at least one candidate vehicle received by the candidate reception unit 13 in association with at least one candidate vehicle on the user interface 105. The display control unit 14 is mainly realized by the processor 101 that operates the user interface 105 while referring to the memory 102 and the storage 103. The “display control unit displays the information regarding the autonomous driving function of at least one candidate vehicle received by the candidate reception unit on the user interface 105” means that the display control unit displays the information regarding the autonomous driving function such that the user can visually perceive which candidate vehicle is the information regarding the autonomous driving function. For example, the display control unit 14 displays icons of the candidate vehicle together with the map on the user interface 105, and displays the information item regarding the autonomous driving function in association with the icon. For example, the display control unit 14 may display a balloon on the icon of the candidate vehicle, and may display the information regarding the autonomous driving function. Alternatively, the user performs an operation for selecting the icon of the candidate vehicle (for example, tap operation), and thus, the display control unit 14 may display the information regarding the autonomous driving function. Alternatively, the display control unit 14 may display the vehicle identification number of the candidate vehicle in association with the information regarding the autonomous driving function.

The acceptance unit 15 accepts a user operation for selecting the dispatch vehicle from at least one candidate vehicle. The acceptance unit 15 is mainly realized by the processor 101 that operates the user interface 105 while referring to the memory 102 and the storage 103. The user operation for selecting the dispatch vehicle is, for example, an operation for tapping the candidate vehicle displayed on the user interface 105.

The dispatch vehicle request unit 16 transmits the information identifying the dispatch vehicle selected based on the user operation to the server. The dispatch vehicle request unit 16 is mainly realized by the processor 101 that operates the communication interface 104 while referring to the memory 102 and the storage 103. The information for identifying the dispatch vehicle is information capable of specifying the dispatch vehicle, and is, for example, the vehicle identification number.

As stated above, in the user device 10, the candidate vehicle together with the information regarding the autonomous driving function is displayed, and the dispatch vehicle is determined based on the user operation.

The server 30 includes a position obtaining unit 31, a vehicle dispatch position obtaining unit 32, a candidate vehicle determination unit 34, a candidate transmission unit 35, a dispatch vehicle reception unit 36, and a vehicle dispatch processing unit 37.

The storage 303 of the server 30 stores the information items of the autonomous driving functions of the plurality of registered vehicles. The registered vehicles are vehicles registered in the vehicle dispatch system 1 in advance. The vehicle identification numbers are allocated to the registered vehicles. The vehicle identification numbers are the IDs for identifying the vehicles. The vehicle identification number may be a number which is allocated in association with a vehicle specific number (a vehicle number described on a license plate, a vehicle body number engraved on a vehicle body, or a physical address allocated to a communication device) by the vehicle dispatch system 1, or may be the vehicle specific number.

FIG. 4 is an example of data retained in the server 30. As shown in FIG. 4, the storage 303 stores a current vehicle position, a current driving state, a current seating state of a driver seat in association with the vehicle identification number. The vehicle position is a position on the map, and is, for example, longitude and latitude. The driving state is any one of the autonomous driving and manual driving. These information items are obtained from the vehicle 2 or a communication infrastructure on a road.

The storage 303 stores the information regarding the autonomous driving function in association with the vehicle identification number. As an example of the information regarding the autonomous driving function, there are the presence or absence of the autonomous driving function, version information of the autonomous driving function, an override rate, the continuity of the autonomous driving, a maximum value of a continuation distance of the autonomous driving (or a maximum value of a continuation time), an average value of the continuation distance of the autonomous driving (or an average value of the continuation time), and a cumulative value of the continuation distance of the autonomous driving (or a cumulative value of the continuation time.

The presence or absence of the autonomous driving function indicates whether or not the autonomous driving can be performed, and indicates information for determining whether or not the vehicle can be performed the autonomous driving. The version information of the autonomous driving function is version information of the autonomous driving system. An override is the driver's operation intervention during the autonomous driving. The override rate is the number of times overrides occur per unit distance. For example, a case where the override rate is “1 (number of times per km) means that one override per km occurs. The continuity of the autonomous driving is an index for evaluating a length from the start to the end of the autonomous driving. For example, the continuity is a ratio of the continuation distance of the autonomous driving to a total traveling distance in the autonomous driving. For example, when the continuation distance of the autonomous driving is 50 km out of 100 km which is the total traveling distance in the autonomous driving, the continuity is 0.5. These information items or original information items of these information items are obtained from the vehicle 2, and are updated in a predetermined timing.

In FIG. 4, for example, vehicle identification number “2A” is associated with vehicle position “longitude: XX, latitude: XX”, driving state “autonomous driving”, seating state of driver seat “presence”, autonomous driving function “presence”, version information “1.0”, override rate “1”, continuity “0.5”, maximum value of continuation distance “50 km”, average value of continuation distance “20 km”, and cumulative value of continuation distance “600 km”.

Subsequently, the dispatch vehicle request unit 16 of the user device 10 transmits the information for identifying the dispatch vehicle selected in the acceptance process (S18) to the server 30, as a dispatch vehicle request process (S20). For example, the dispatch vehicle request unit 16 transmits the vehicle identification number to the server 30.

The dispatch vehicle reception unit 36 of the server 30 receives the information for identifying the dispatch vehicle from the user device 10, as a dispatch vehicle request acceptance process (S108).

The input module operates a computer so as to accept an input from the user. The arithmetic processing module is a module that performs the arithmetic processing. Functions realized by executing the main module, the input module, and the arithmetic processing module are the same as the functions of the user device 10 or the server 30. For example, the server program and the user device program are provided by a non-transitory computer-readable recording medium such as a ROM or a semiconductor memory. The server program and the user device program may be provided via a network.

(Conclusion of First Embodiment)

According to the vehicle dispatch system 1, the information regarding the autonomous driving function of at least one candidate vehicle is displayed in association with at least one candidate vehicle on the user interface 105 of the user device 10.

The candidate transmission unit 35 of the server 30 calculates one or a plurality of estimation routes, and an estimation required time from the vehicle dispatch position to the destination based on the vehicle dispatch position, the destination, and the map information. For example, the map information is stored in the storage 303, and information capable of determining whether or not to perform the autonomous driving is embedded. For example, the information capable of determining whether or not to perform the autonomous driving is information (positional information of a lane boundary line, positional information of a pole, traffic regulations, or the like) required in the autonomous driving. On the estimation route, a section in which the information required in the autonomous driving is included is an autonomous driving enabled section, and a section in which the information required in the autonomous driving is not included is an autonomous driving disabled section. Alternatively, on the estimation route, the reliability which is equal to or greater than a predetermined value cannot be secured in a section in which data is insufficient cannot secure, this section may be determined as the autonomous driving disabled section. Alternatively, information indicating whether or not to perform the autonomous driving may be allocated to each section in advance. The candidate transmission unit 35 determines the autonomous driving enabled section or a section in which it is necessary to perform the manual driving for each estimation route, and generates data obtained by associating the information with the candidate vehicle. The candidate transmission unit 35 transmits the generated data to the user device 10. Other functions of the server 30 are the same as those in the first embodiment.

(Authentication Process)

Hereinafter, an example of an authentication method is disclosed. FIG. 12 is a flowchart showing an example of an authentication process. For example, the flowchart of FIG. 12 is performed in timing when the vehicle dispatch process shown in FIG. 7 or 10 is ended.

As shown in FIG. 12, the generation unit 39 of the server 30 generates the authentication information, as a generation process (S140). Subsequently, the authentication information transmission unit 40 of the server 30 transmits the authentication information generated in the generation process (S140) to the user device that transmits the information for identifying the dispatch vehicle and the dispatch vehicle, as a transmission process (S142).

At least one of the user device 10 and the dispatch vehicle of the vehicle dispatch system 1 can authenticate the combination of the dispatch vehicle and the user device by using the authentication information.

Fourth Embodiment

A vehicle dispatch system 1 according to a fourth embodiment is different from the vehicle dispatch system 1 according to the third embodiment in that a part of the authentication function is different, and other points are the same. The same contents in the fourth embodiment as those in the third embodiment are not repeated.

FIG. 13 is a block diagram showing an example of an authentication function of the vehicle dispatch system 1 according to the fourth embodiment. As shown in FIG. 13, the server 30 further includes a determination unit 38.

When the vehicle dispatch process of FIG. 7 or 10 is ended, the determination unit 38 of the server 30 determines whether or not the dispatch vehicle at the time of dispatching the vehicle is a manned vehicle. The determination unit 38 is mainly realized by the processor 301 operated while referring to the memory 302 and the storage 303. For example, the determination unit 38 reads the seating state of the driver of the dispatch vehicle, and determines whether or not the dispatch vehicle is the manned vehicle while referring to the storage 303. That is, whether or not the dispatch vehicle is the manned vehicle means whether or not the driver is seated on the driver seat.

When the determination unit 38 determines that the dispatch vehicle at the time of dispatching the vehicle is the manned vehicle, the generation unit 39 of the server 30 does not generate the authentication information. The generation unit 39 generates information for confirming that the combination thereof is correct through conversation between the driver and the user instead of the authentication information, and presents the generated information to both the driver and the user. Information of the dispatch vehicle and information of the user are used as an example of such information. For example, the vehicle identification number of the dispatch vehicle, the vehicle type, and the information of the driver are used as the information of the dispatch vehicle. For example, a user ID, user device specific information (telephone number, fixed address, or the like) are used as the information of the user.

The authentication information transmission unit 40 transmits the information of the dispatch vehicle to the user device 10, and transmits the information of the user to the dispatch vehicle. In this case, the device authentication unit 18 of the user device 10 and the vehicle authentication unit 26 of the vehicle 2 do not perform authentication operations. Other configurations are the same as those in the third embodiment.

(Authentication Process)

When the vehicle dispatch process shown in FIG. 7 or 10 (S150: YES), the determination unit 38 of the server 30 determines whether or not the dispatch vehicle at the time of dispatching the vehicle is the manned vehicle, as a determination process (S152).

When it is determined that the dispatch vehicle at the time of dispatching the vehicle is the manned vehicle (S152: YES), the generation unit 39 of the server 30 generates the information of the dispatch vehicle and the information of the user, as an information generation process (S158). The authentication information transmission unit 40 of the server 30 transmits the information of the dispatch vehicle to the user device 10 and transmits the information of the user to the dispatch vehicle, as a transmission process (S160). Accordingly, it is possible to confirm that the combination thereof is correct through the conversation between the driver and the user.

When it is determined that the dispatch vehicle at the time of dispatching the vehicle is the unmanned vehicle (S152: NO), the authentication information generation process (S154) and the authentication information transmission process (S156) are performed. The authentication information generation process (S154) and the authentication information transmission process (S156) are the same as the generation process (S140) and the transmission process (S142) of FIG. 12. That is, the authentication process (S54) and the authentication process (S201) of FIG. 12 are performed after the authentication information generation process (S154) and the authentication information transmission process (S156) are performed.

When the vehicle dispatch process of FIG. 7 or FIG. 10 is not ended (S150: NO) and the authentication information generation process (S154) is ended, if the transmission process (S160) is ended, the flowchart shown in FIG. 14 is ended.
